To all whom it. magi concern:

Be it;kuownthat 1,.ROBERT. A. GALLY, a

is citizen of the United States, residing at Gin,

cinnati, ini-th'e .ac ounty of Hamilton, State of Ohio, have-invented certain newand .useful Im rovement-s Web-Guiding Devices, of which. the" {following-i is a specification.

pliea'ted screwsshaft movements for shifting the roll carrying :the. web to be guided, or

ngitudinal spring pressure a have hadlz against such ollzwith consequent necessity of camaction against said pressure, and in music self playing structures have employed many parts to accomplish what isnow done, in a slmpleiorm. In the drawings F1 re 1 is a front view. of music player roll ox with -present new automatic guiding: device included; Elg. 2 is a plan viewofsameyand Fig. 3 a view of the right end. 1

The traveling-web, which in this showlng is a perforatedmusic-sheet 1, is usually carried onitsspool 2 which when in use in the apparatus is. inserted between and held in revoluble position. by clutch spindles 3 and 4 which'areopposed to each other at the two sides of the,box, but in one axial line. For easy insertion of such spools as 2, one of the spindles as 3, is usually provided with longitudinal pressure toward the other spindle, as

4, by means. of a spring, as 5, which ordinarily acts onsuch spindle 3 relatively to a fixed part of; the apparatus, as the box 6, in

which case. any longitudinal adjustment of the spindles 3 and 4 to set the'particular transverse position of .the sheet 1, requires such adjustment ,tohave a steady :resistance against theiconstant pressure of such spring action. m1

With autOmaticsheet guides employing pneumatic or equivalent adjustingaction to the spindles, some cam on wedge has been re quired to avoid a constant changing, error or vibration of such longitudinal adjustment of said spindles. .Thisis now avoided by guiding the longitudinal position of the two spindles 3 and 4: by means of a yoke, frame or unitarily moving member or means .7 coact ng with both said spindles at once, and

haying the spring 5 acting between the spindle 3 and the said yoke or unitarily moving member or means 7 independent of the box 6 or other fixed part of the apparatus, so that said yoke or unitary means 7 can be power and easy .parts employed.
